hoist hook - ANSWER - a curved implement used to quickly and temporarily connect rigging to a load or lifting equipment boom tip platform - ANSWER - personnel platform mounted to a crane boom ASME - ANSWER - American Society of Mechanical Engineers OSHA - ANSWER - Occupational Safety and Health Administration NESC - ANSWER - (National Electrical Safety Code) standard published the IEEE used throughout the outside line industry FMCSA - ANSWER - (Federal Motor Carrier Safety Administration) agency in the DOT that covers safety regulations for mobile cranes operated in interstate commerce Competent person (OSHA definition) - ANSWER - A person who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary,
hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them. Qualified person - ANSWER - A person who, by possession of a recognized degree, certificate, or professional standing, or by extensive knowledge, training, and experience, has demonstrated the ability to solve or prevent problems relating to a certain subject, work, or project. OSHA 1926.1408 table A - ANSWER - used to determine minimum clearances during assembly and disassembly operations near energized power lines (also for unqualified workers MAD) OSHA 1926.1411 table T - ANSWER - used to determine minimum clearances while traveling under or near energized power lines with no load before transporting a crane the boom must be - ANSWER - fully retracted, lowered and properly stowed
toolbox installation - ANSWER - not allowed without permission of the crane manufacturer lift plan - ANSWER - documented evaluation of the potential hazards and the equipment and procedures required to perform it safely before a crane enters a jobsite - ANSWER - job site hazards must be identified and addressed minimum swing clearance (for the boom and counterweights) - ANSWER - 2 feet ground condition - ANSWER - slope, compaction and firmness of the ground that determine the ability of the ground to support the crane minimum distance a crane operator should stay from the edge of a slope - ANSWER - 1 foot back for every foot of depth
unknown voltage minimum distance - ANSWER - 20 feet outrigger pads minimum size - ANSWER - 3 times the float size during a crane to powerline contact, the operator should first: - ANSWER - warn others underground obstructions - ANSWER - old septic systems, buried tanks, sewer mains, manholes, voids, loose soil, etc OSHA 1910.269 - ANSWER - minimum approach distance for cranes table (only for qualified electrical workers) OSHA 1926.1408 A - ANSWER - minimum approach distance for cranes (for unqualified electrical workers) dedicated spotter or signalperson - ANSWER - required if a crane boom maximum length at any radius could come within the limit of approach
